If that is available on some card, I'd love to know. You might > get the software written for your card in return :) Have you seen the stuff done for Linux (bttv) that uses the bt848 to grap the VBI info and then decode teletext from the sampled lines ?? THAT is a cool concept, and a good job done! -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Søren Schmidt (sos@FreeBSD.org) FreeBSD Core Team Even more code to hack -- will it ever end ..
